User manual - DATA RECORDER SRD-99 and cooperating software
This is a class A unit. In a residential or a similar area it can cause radio
frequency interference. In such cases the user can be requested to use
appropriate preventive measures.
Carefully check that the isolation used with the unit ( Fig. 3.1 ) meets the
expectations and if necessary use appropriate measures of overvoltage protection.
Additionally, insure the appropriate air and surface insulation gaps when installing
(
Tab. 3.1
).
Range of operating voltage Air gap [mm] Surface gap [mm]
Up to 50V RMS or DC 0,2 1,2
Up to 100V RMS or DC 0,2 1,4
Up to 150V RMS or DC 0,5 1,6
Up to 300V RMS or DC 1,5 3,0
